The Biden administration is setting aside $291 million in grants to transition the aviation industry to zero-emission, sustainable fuel sources.

Around $244 million of those funds will go toward 22 projects related to producing, transporting and testing sustainable aviation fuels (SAFs), with the remaining money going to 14 projects developing other low-emission aviation technologies.That includes $2.7 million to the University of Illinois to build a test facility for electric airplane technology, and $16.8 million to renewable biofuel company Gevo to transition an existing fuel facility to produce SAFs.

“These grants will help put the world on a path toward decarbonizing aviation while fostering domestic economic growth and ensuring the U.S. retains its global leadership in aviation," U.S. transportation secretary Pete Buttigieg said in an August 23 news release.

SAFs can be sourced from alternatives to fossil fuels such as fats and oils from food and yard waste, and could potentially cut greenhouse gas emissions by up to 94%, according to the U.S. Department of Energy.  The Biden administration is currently targeting 2050 to achieve net-zero greenhouse gas emissions from the aviation sector.
